Toughening of chlorinated polyvinylchloride with acrylonitrile-butadiene-styrene graft copolymers

Abstract

In this article, a series of acrylonitrile‐butadiene‐styrene (ABS) graft copolymers with polybutadiene (PB) particle sizes ranging from 66 nm to 304 nm were prepared. Toughening of chlorinated polyvinylchloride (CPVC) with ABS graft copolymers was investigated. The results showed that PVC, as a compatibilizer, made the miscibility of CPVC/ABS blends better. PB particle size had significant influence on the ductility of CPVC/ABS blends. There was obvious synergetic effect in the bimodal system. From scanning electron microscopy (SEM), it was found that the dispersion of ABS graft copolymers in the matrix was dependent of PB particle size, and the morphology of CPVC/ABS blends was consistent in the ability to explain properties.

Effect of core–shell structures of acrylonitrile–styrene–acrylate (ASA) terpolymer on the properties of poly(vinyl chloride) (PVC)/ASA blends: Miscibility, toughness, and heat resistance

“…Therefore, it is expected that ASA terpolymer can also work as an impact modifier for rigid PVC. Ren and coworkers studied the effect of AN content in SAN shell on the toughness of PVC/ASA binary blends and PVC–ASA–DOP blends. They found that the impact strength of the PVC/ASA blends and PVC–ASA–DOP blends increased and then decreased with the increasing AN content in the SAN shell.…”
